(3R,6R,12R,20S,24S)-3,6,12-Triacetyl-20,24-epoxydammarane-3,6,12,25-tetraol

The title compound, C36H58O8, was prepared from 20(S)-protopanaxatriol, which was degraded from Panax quinquefolium saponin with sodium in glycerine, extracted and seperated by flash chromatography. Three six-membered rings are in chair conformations, the five-membered ring is in an envelope form an...
